I have two identical hard drives connected as master and slave on primary ide channel, and two optical drives on secondary ide. The problem is that the slave hard drive will only run in pio mode, and not udma mode 5 (as the primary does). The upshot of this is that any file transfer to or from my slave drive results in 100% cpu usage, and it's very annoying. As I have an uptodate motherboard do you think that putting a hdd on each ide channel with optical as slave would speed things up?
I think you may have to re-detect the drive. In order to do this,it has to be physically changed on the data cable(s).
If it were me, I would temporarily disconnect your optical drives. Put the suspect drive on it's own data cable as Master and boot the machine. Now check and see if you still have a problem. The drive will now have been re-detected and on shut down, can be placed back to it's original postion, to be re-detected again. Simply switching the computer on and off will not produce the desired results.
The Hibernation feature in XP, has resulted in some reports of strange behavior, and if your using that, personally, I would disable it.
